How to remove heater control panel on 115?
 

Well, I've conquered the the instrument cluster lights of my 115 ('76), now to the heater control panel. Question is, how do I get the darned panel off to reach the light(s) and plastic bits that conduct the light to the heater levers and fan switch? I've gotten as far as removing the fan switch knob, the spanner nut under that, and the air-directing grille, but now it looks like I need to burrow under the dash to release something that holds the whole works in there. Any clues? Is it possible I could remove the plastic grilles on the sides of the center divider and reach up in there that way?

Again, thanks in advance!

Not sure how similar the 115 is to a 108 in regards to the heater controls, but you may have to have the instrument cluster and glove box out. On the 108, with both item removed you gain access to two 10mm nuts that retain the facia for the heater control.
